Application filed July 15,

This invention relates to work supports and is illustrated as embodied in a fastening inserting machine having a novel work support arranged to facilitate the presentation of a work piece successively in differentrelato fill the area at the bottom of the counter,

and when fastened in place holdingthe sides or the counter against transverse displacement. The illustrated work support was developed primarily for the purpose of facili tating the handling of tucks and counters while they arebeing fastened togetherand the invention is accordinglydisclosed hereinwith particular reference to that workand as embodied in a staple inserting machine adapted for stapling-tucks and counters together. It should be understood, however,

that this is merely an exampleot a: machine in which the invention may be embodied, and that the invention'is' not limited'in its utility either to embodiment in'fastening inserting machines "or, necessarily, to use in machines for operating" on tucks and counters.

It is an object of the'present invention-to provide an improved work support arran to facilitate the presentation of a war-11: piece; 7

suchas one consisting of a tuck and con successivelyin a plurality of different posrtions relatively to the operating instrumentalities 'of'a mac-hine'which is to operateu'pon the 1 work piece. Preferably, and as illustrated; the work support is provided with positioningmembers arranged to engage the work piece and movable therewith :to control 7 its positionrelatively to the operating inst-rumentalities ofthemachine as the work piece is moved between the performance of successive operations thereof.

In accordance witha'featureof the invenv tion the work piece-positioning members of the work sunportof the llustrated machine are mounted-for movement both forwardly ve rsely thereoi Sprin s being prOVided tend 1927. Serial No. 206,017.

Fig. 1 of the drawings illustrates the work support as embodied in a staple fastening machine of the type disclosed in Letters Patent of the United States No. 1,016,930, granted February 13, 1912 on an application of Villiam I-I. Borden. Since the present invention is in no way concerned with the details of the fastening inserting instrumentalities of the machine, there is no necessity for describing them in this specification except to state that the fastenings are driven by suitable means through a throat opening in a nozzle with which the headof the macnine is provided,

instrumentalities being supplied from a suit ably. operated cam shaft 12. For further details of the illustrated machine reference may be had to said Letters Patent Ila-1,016,930. The fastening inserting instrumentalities of the machine are carried by a head 13 mounted upon the upper endof a column 14 which also supports a bracket 16 (see particularly Fig. 2) provided with a vertical sleeve 18 containing a bearing fora post 20 mounted for vertically sliding movement and provided with a collar 22 forming an abutment for the upper end of a heavy coil spring 24 surrounding the post. 20 and bearing at its lower end against a seat 26 formedat the upper end of'the sleeve'18- To the upper end of the post 20 is clamped another. bracket 28 having at itsupper end a socket in which is clamped thelower end of a support 30 for a clenching anvil 32. y i

As is common in machines of this type, mechanism is provided to move the post '20 upwardly so as to clamp the work piece between the clenching anvil32 and the nozzle 10 when a fastening is being driven, and to move the post 2-0 downwardly to release the clampingpressure upon the work piece while the latter is moved between the insertion of successive fastenings. This mechanism in cludes a lever 34 (Figs. 1 and 2) fulcrumed at 36 to the bracket 16 and bearing at its for ward end in a notch 38 formed in the horn post 20. At its rear end the lever 34 is bored loosely to receive a rod 40 (Fig. 1) having to the lever 34 and also having clamped thereto a second collar 44some distance above the rear. end of the lever 34. A spring 46, not

so stiff as the spring 24, surrounds the rod 40,

bearing at its upper end against the collar 44 and at its lower end against the lever 34. At its upper end the rod 40 is pivoted to a lever 46 rocked at suitable times in the operation of the machine by a cam carried by the shaft 12. Thus it will be seen that upward movement of the rod 40 positively rocks the lever 34in a counter-clockwise direction as shown in Fig. 2, thereby pulling the post 20 downwardly against the action of the sprin 24 while downward movement of the rod 40 rocks'the lever 84 impositively in a clockwise direction as viewed in Fig. 2, since the spring 46 can yield when it is no longer possible further to raise the anvil 32 and its support 30.

Work positioning members arranged to facilitate the presentation of a counter and a tuck to the fastening inserting instrumentalities of the machine will now be described. A short horizontal shaft 48 has a bearing in the bracket 28', extending transversely of the machine. A second shaft 50 extending from the front to the rear of the machine in a direction at right angles to the shaft 48 is mounted Clamped to the median portion of the shaft 50 is a work positioning member comprising an upwardlyextending arm 54 carrying at its upper end a cylindrical member 56 formed to engage a semi-circular notch A in the forward end of a tuck B (Fig. 4). Glamped to the forward end of the shaft 50 (at the left as shown inFig. 2) is a bracket 58 to which is secured by a screw and slot connection 59, an arm 60 extendingtransversely (to the left in Fig. 1) and then rearwardly of the machine andformed at its other end with a hearing to which is adjust-ably clamped'a second work positioning member comprising an upwardly extending rod 62 which carries at its upper end a button-like member 64 having a flat top serving as apositioning surface to engage the flat inner surface of a tuckat the rear thereof and substantially in engagement with the rear surface of a counter to which the tuck is to be fastened.

The bracket 28 carries at its upper end a stop 66 adjustably mounted by a screwand slot connection 67 and provided with a transversely extending positioning surface 68 and a forwardly and rearwardly extending positioning surface 70 (Fig. 3) positioned in the path of movement'of the arm 54 as the latter is rocked about the axes of the shafts 48' and 50 respectively. A spring 72 anchored at one end to a collar 7 4 secured to the shaft 50 and at the other end to the yoke 52 tends to rotate the shaft-50 in a direction to h ld the arm 54 i in engagement with the positioning surface 70 of the stop 66. A similar spring 76 anchored at one'end to the bracket 28 and at the other end to "a collar 78 secured to the shaft48 tends to rock the shaft 48 in a direc tion' to'cause the armu54 to engage theposiat E has been inserted, the operator, who;

The rod 62 with its't-uck engaging member 6a partakes cause the cylindrical member 56- carried' by the arm 5 when engaged in the notch A in the forward end of a tuck B, to position the tuck and a counter G,"the inncrsurface of the flange D of which hasbeen properly positioned manually relatively to the tuck, for the insertion offasteningsto secure'the two together, in such a position relatively to the nozzle lO and the anvil 32 that, with the parts in the position they naturally assume under ing inserted'will take the position shown in solid lines at E in Fig. 4'.- By reference to that figure it will also be observed that the member 64 carried by the rod 62 is so adjusted as to' engage the inner surface of the tuck B at the rear of the tuck and substantially in engagement with the rear-end surface ofthe counter C. After the fastening shown preferably maintains his hold upon the counter C during the entire operation, moves the counter transversely of itself (rearwardly of the machine), thearm 54 and the rod 62 with the member 64 yielding against the action of the spring 76.nntil the side wall of the counter nearest theoperator'brings up' against the anvil'32.

It will be noted that while these staples are being inserted the positioning of the staples widthwise of the counter is determined with'a sutiicient degree of accuracy either by the position ofthe notchengaging member 56 carried by the arm 5 L (when staple E is being inserted), by the side surface of the counter when staples F and G r are being inserted, or'by both when staple is being inserted, while the button-like member 64 carried by the upper end of the rod '62 serves to facilitate the proper positioning of the tuck relatively to the flange of the counter heightwise of the counterand serves also tomaintain the length of the counter generally transversely of the machine."
